The electronic treadle, can detect when a train stops so that, for example, routes and level crossing barriers can be released, it is also a superior replacement to a mecanical treadle. The only moving part of the treadle is a relay in the evaluation unit.

If the dynamic wheel pressure exceeds a preset level, a change-over relay will be energized for 5 seconds.

The evaluation unit has fixed settings for different types of rails. No calibration is needed on installation. The tradle  consists of a sensor bolted to one of the rails and an evaluation unit with a DSP processor and other electronics installed alongside the track. Other functions for example axle counter are possible by modifying the software.
